Abstract : The differential cross section for molecular beams with uniform and nonuniform velocities is obtained in power series in powers of theta and pi  theta (where theta is the scattering angle in the centerofmass system) for intermolecular potentials of the form U(r) = lambda (1/r to the nth power); and they are numerically calculated for integral n between 6 and 14. The quantum mechanical effects are neglected. The cross sections obtained are compared with the experimental results of Knauer for the scattering of a H2 beam in Hg gas and the intermolecular potential between H2 and Hg is determined to be U(r) = 273k (3.5/r) to the 7th power, (r in A, k = Boltzmann constant).
